Securing, Hardening, and Optimization(Linux Server)

We have a single web server running Linux Fedora Core 2 and Plesk Reloaded. We have just recently put the server online. It is now in production and is fully 100% up and serving websites, but it does need Optimized, Hardened and Secured. This job will also include reviewing our routers configuration and making necessary suggestions concerning its security and configuration. We need an experienced consultant to ssh in and do whatever is needed to make it as stable and secure as it can be, and also to optimize it according to our needs and according to our connection type. All appropriate login information and server info will be given. The work must be scheduled and completed in conjunction with me via yahoo messenger. We will communicate from start to finish. If you can not do this job in this manner please do not bid. Also we need someone who speaks and can fully understand English. A security agreement must also be e-mailed to you, printed, filled out, signed, scanned, and e-mailed back to us in PDF form before passwords and confidential materials are handed over. Our customers security is our main concern on this job. For the experienced Linux System Admin this should be a breeze. Also, keep in mind we are looking for someone to do this on a regular basis, so consider this job an interview if interested. Our budget for this job is between 15-40 USD. Good Luck and we look forward to accepting your reasonable bid! :-)
